Pennell called dispatchers about Enchautegui-Otero’s car, which had hit a tree.

Horstman says emergency responders found the deputy and Enchautegui-Otero "with significant injuries" several minutes later after another vehicle left the road and struck them.

A photograph from the sheriff’s office appeared to show tire impressions in the grass near Pennell’s patrol car. Horstman says authorities were searching for a driver whose vehicle had front-end damage.

Enchautegui-Otero was pronounced dead at a hospital. Horstman says Pennell was hospitalized with serious injuries.
